Abstract
Skin and feather temps. were taken with a contact thermocouple and a Hardy dermal radiometer, in White Leghorns and New Hampshires, at environmental temps. of 74[degree], 80[degree], 86[degree] and 90[degree] F. Deep body temp. as well as skin temps. varied within the range studied. Highest skin temp. occurred on the femur and breast, while the temps. of comb, wattle, and shank (anterior) were lower and varied more with environmental temp. Gradients existing in skin temp. may be related to location on the bird and to air temp. A negative correlation between temp. of either comb or shank and deep body temp. demonstrates that they act as heat-loss mechanisms.Keywords
